Much of these heated sentiments are linked to the controversial email leak that rocked the Democratic National Committee (DNC) and led to the resignation of its chairwoman, Debbie Wasserman Schultz, on the eve of the convention.

Schultz also spoke on Monday and, like Bernie, experienced a chorus of boos during her remarks.

The 20,000 emails released by Wikileaks, now referred to as the DNC leak, showed the Democratic National Committee had a strong preference for Hillary Clinton and worked to find ways to undermine the campaign of Bernie Sanders.

In one of the more controversial examples, a top staffer at the Democratic National Committee questioned Sanders' Jewish faith and heritage and suggested painting him as an atheist to hurt him with certain segments of voters.

Needless to say, these revelations generated widespread anger, particularly among Sanders supporters. There were many in Sanders camp who accused the DNC of having a strong bias against the Vermont senator throughout the election cycle. They were frequently dismissed and characterized as paranoid conspiracy theorists.

For 12 months Bernie supporters have been screaming that the DNC was outrageously biased. We were told we were ridiculous the whole time.

Why This Presidential Election Is A Joke
